Never mind - I think I have it - needed to replace uses of 
cpp_dec_float_max_digits10 with cpp_dec_float_total_digits10 which does what 
it says, where as cpp_dec_float_max_digits10 doesn't anymore.  With that 
change the tests I've run pass so far.... but they're still running.

Maybe we should rename cpp_dec_float_max_digits10 to something else?   BTW, 
what's the logic behind the +1 in defining that one?  Not that it makes much 
difference either which way.

Cheers, John.
